Chlorinated water and Teeth

超過 26% 的競技游泳選手和 10% 的休閒游泳選手出現牙齒侵蝕。競技游泳選手的損傷發生在前牙的 Labial 和 Palatal 表面，而休閒游泳選手的侵蝕僅發生在Palatal表面。儘管池水的pH值是中性的，但 Hydroxyapatite 是不飽和的。

Dental erosion was found in more than 26 % of the competitive swimmers and 10 % of the recreational swimmers. The lesions in competitive swimmers were on both the labial and palatal surfaces of the anterior teeth, whereas erosions in recreational swimmers developed exclusively on the palatal surfaces. Although the pH of the pool water was neutral, it was undersaturated with respect to hydroxyapatite.

The labial surface is the aspect of the maxillary central incisor tooth that faces towards the lips and vestibule.

The palatal surface of a tooth is directed toward the palate.

Extended exposure to chlorinated water can lead to erosion of tooth enamel. After swimming, you can rinse your mouth with tap water to wash away any remaining pool water that can damage your teeth. Also, you should brush with fluoride toothpaste twice a day.

The general consensus is that the optimal pH value for pool water is 7.4.
